Orange Demarcation Fabrics

IWT Cargo-Guard is proud to introduce Geotex® OR DND, the first printed NONWOVEN demarcation geotextile. Geotex OR DND is a highly visible orange nonwoven geotextile fabric printed with the text “DANGER DO NOT DIG / PELIGRO NO EXCAVAR”

Turbidity barriers, also known as floating turbidity curtains, silt curtains, silt barriers or silt screens, prevent the migration of silt and sediment from a work site into nearby waterways. Applications include dredging, pile driving, remediation and shoreline restoration.

Geosynthetics can be used alone or together to significantly extend the life of everyday structures providing one or more of the following functions: separation, reinforcement, filtration, drainage, containment, surface erosion control, and protection.

PROJECT SPOTLIGHT

When JF Brennan and Envirocon needed to design a custom turbidity curtainlayout for the Ashland/Northern States Power Superfund project in Ashland Wisconsin, IWT Cargo-Guard and Spilldam Environmental were called upon to come up with a curtain system that would work and satisfy the oversight engineers and the regulatory authorities. The material to be dredged NAPL (non-aqueous phase liquids) can be particularly difficult to work with as it coats and clogs almost everything it comes in contact with. By working closely with the engineering company and the onsite contractors,JF Brennan and Envirocon, a multi-tiered approach was designed to provide a fail safe containment system. The system consisted of bedload baffles, carbon curtain, and turbidity barriers / silt curtains designed specifically for this project site.
